TauP TimeΒΆ
TauP Time takes a either a {texttt .taup} file generated by TauP Create or a velocity model in {texttt .nd} or {texttt .tvel} format and generates travel times for specified phases through the given earth model.
The usage is:
Usage: taup time [arguments]
or, for purists, java edu.sc.seis.TauP.TauP_Time [arguments]
Arguments are:
-ph phase list -- comma separated phase list
-pf phasefile -- file containing phases
-mod[el] modelname -- use velocity model "modelname" for calculations
Default is iasp91.
-h depth -- source depth in km
--stadepth depth -- receiver depth in km
--scat[ter] depth deg -- scattering depth and distance
Distance is given by:
-deg degrees -- distance in degrees,
-km kilometers -- distance in kilometers,
assumes radius of earth is 6371km,
or by giving the station and event latitude and lonitude,
assumes a spherical earth,
-sta[tion] lat lon -- sets the station latitude and longitude
-evt lat lon -- sets the event latitude and longitude
or by giving the takeoff angle,
--takeoff angle -- takeoff angle from the source
zero is down, 90 horizontal, 180 is up
or by giving the ray parameter,
--shootray param -- ray parameter from the source in s/deg
up or down is determined by the phase
--first -- only output the first arrival for each phase, no triplications
--rayp -- only output the ray parameter
--time -- only output travel time
--rel phasename -- also output relative travel time
--json -- output travel times as json
-o [stdout|outfile] -- output is redirected to stdout or to the "outfile" file
--prop [propfile] -- set configuration properties
--debug -- enable debugging output
--verbose -- enable verbose output
--version -- print the version
--help -- print this out, but you already know that!
The modelname is from modelname.taup
, a previously created file
from TauP Create or a modelname.nd
or modelname.tvel
velocity model file.
If there is insufficient information given on the command line, then you start
in interactive mode, otherwise it assumes you only want one set of times.
The phases are specified on the command line with the -ph option, in a phase file with the -pf option, or in a properties file. The model, phases, depth and distance can be changed within the interactive section of TauP Time.
For example:
taup time --mod prem -h 200 -p S,P --deg 57.4
gives you arrival times for S and P for a 200 kilometer deep source at a distance of 57.4 degrees.
